Abstract

When ignition is on, a shift position is a neutral position, and shut-down of the inverter is cancelled in a state that a short circuit fault occurs in any phase among multiple phases of the inverter, the electrically driven vehicle performs a first ON control to turn on upper and lower arms in any arbitrary phase among the multiple phases. When an abnormality is detected in the inverter due to the first ON control, the electrically driven vehicle performs a second ON control to turn on upper and lower arms in a different phase from the phase of the first ON control.

Claims

exact text as granted — not AI-modified
The invention claimed is: 
     
       1. An electrically driven vehicle, comprising:
 a motor configured to input and output a power for driving; 
 an inverter configured to drive the motor; 
 a power storage device configured to supply electric power to the inverter; and 
 a control device configured to shut down the inverter in response to detection of a short circuit fault of the inverter, wherein 
 when ignition is on, a shift position is a neutral position, and shut-down of the inverter is cancelled in a state that a short circuit fault occurs in any phase among multiple phases of the inverter, the control device performs a first ON control to turn on upper and lower arms in any arbitrary phase among the multiple phases, and 
 when an abnormality is detected in the inverter due to the first ON control, the control device performs a second ON control to turn on upper and lower arms in a different phase from the phase of the first ON control. 
 
     
     
       2. The electrically driven vehicle according to  claim 1 ,
 wherein the control device shuts down the inverter when an abnormality is detected in the inverter, and 
 when an abnormality is detected in the inverter due to the first ON control, the control device cancels the shut-down of the inverter and subsequently performs the second ON control to turn on the upper and lower arms in the different phase from the phase of the first ON control.
